Syllabus and past papers

The British Biology Olympiad (BBO) complies with the rules of the International Biology Olympiad (IBO), the balance of the various topics, the style of the papers and the questions conform to the IBO syllabus which is very broad.

It is clear that most candidates will not have covered all of the syllabus, but no-one is at a disadvantage as this is a similar issue for everyone who enters. Different sections will be covered or omitted according to which UK examination board and options are being studied.
